GEORGE RGER PROVSE, OF MOXTREAL, QUEBEC, CANADA.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 295,197, dated March18, 1884.

' Application led November 23, 1883. (Xo niodeLl To all wlw/iii t may'concern.:

Be it known that I, GEORGE Roeien Peor Tsn, of the city of Montreal,District of Montreal, Province oi' Quebec, Canada, have invented certainnew and useful Improvements in the Construction of Refrigerators; and Ido hereby declare that the following is a full, clear,

and exact description of the same.

This invention consists, principally, in a new manner of forming aninnerliningfor refrigerators, said inner lining being an eXcel lentnon-conductor of hea-t, a non-corrosive, and gives all the Jdnish andbeauty of a polished-1narble lining, and is much more easy of being keptclean than any of the metallic linings at present in use.

My said invention may be brieiiy stated to be forming a lining to arefrigerator of sashworlr, similar to window-sashes to hold glass, withthe said glassplaced therein, as usual, and the whole filled up orbacked with plaster 'or plastic compound, which, when it has set andhardened, becomes practically one substance with the glass iining andsash-work, giving at the same time strengthto the glass to withstand anyblows it may be subjected to, and imparting a heat non-conductive andbinding or attaching medium to the whole.

My said invention is applicable to almost all, if not all, forms ofrefrigerators; therefore by drawings showing how it is applied to oneform, the manner of appling it to others will be understood.

My invention further consists in providing a removable tank to catch thewater formed by the melting ice, to enable it to be cleaned and freefrom bad odor, which cannot wcll be done when the tank is secured inplace.

In the drawings hereunto annexed, similar o letters of referenceindicate like parts, and Figure l is a front elevation of an outercasing of arefrigerator.I Fig. 2 is avertical sectional elevation onlines .e az, Figs. l and 3, of the outer casing shown in Fig. 1, and ofthe icebox andniyinven'tion applied thereto. Fig. 3 is a plan of bothFigs. l and 2, with covers removed. Fig. 4: is an outline isometrical diagram of the general configuration of inner lining as applied to arefrigerator of the con- Figs. 5 and 6 are details of construction.

Letter A is the outer casing; B, the door; C, the ice-box; D, the coverof outer casing hinged at E. F is the cover of the ice-box, hinged at G,all of which are constructed and arranged in an ordinary manner.

To apply my invention to the aboveconstruction, I forni a sash-work, H,by combining sash-i`rames together tov forni (see Figs. 2, 4, and 5) abottom, l, two sides, K, and a back, L. The front, M, is formed of asingle sashfrnie, H, attached on the door B. In the sash frame-work Iplace squares of glass N, and iill up at the back of the glass the sashframe-work with plaster or plastic compound O, those compounds whichwill set hard in a shoit tim e being preferable. The section sh own inFig. 5 may be taken for a section on line g; y, Fig. 4, or it maybetaken to be a section at line Z through the back and part of the bottom.I much prefer to have the plaster or plastic compound white, or nearlyso, as it reflects the light much better and enables the articles withinthe refrigerator to be seen more clearly; it also shows better if therefrigerator is in a clean or dirty state. The glass gives a beautifulsmooth and easilycleaned surface, 'and the plaster or plastic compoundgives not only a good non-conductor of heat, but also great strength tothe glass, so that it will stand very considerable concussions or blowswithout any danger of being broken.

Figs. 5 and 6 show two different ways of forming the angles of the innercasing. By a inere look at the drawings these will be understood withoutany further description, being equivalents ci each other.

The top of the inner casing (shown in Fig. 4) may be conigurated toagree with any desired form of ice-box C employed.

A is a strengtheningbar.

Although, as hereinbefore set forth and shown in the drawings, therefrigeratorI described consists of three principal partsan outer andinner casing and ice-boX-yet if it is so desired the inner and outercasing may be made in one by attaching battons B to the sash-work, asshown in Fig. 5,

It would be useless and tedious to endeavor to give even a generaldescription of the various forms in which n iy invention may beemployed, for such forms have nothing to do with the invention itself,except in so far as will be hereinafter claimed.`

It will be observed that, as shown 'in the drawings, the back L of theinner casing is at a distance from the back L/ of the outer casing.rllhis is to give room for a tank, P, placed in an opening formed in theback L. The'tank projects into the casing A, as shown in Fig. 2, and bydotted lines in Fig. 3. This tank is secured in place by commoncupboard-buttons R. The said tank is preferably formed of sheet metal,and may be provided at or near its bottom with a tap or other means ofdraw# ing off the water accumulating in it. vAs the ice melts in the boxC the water passes through the opening S over the projection T and fallsinto the tank P.

V are openings for the circulation of the air. formed in the front sideoi' the ice-'box G.

I am aware that it is not new to line refrigerators with glass and fillin the spaces between the glass and outer casing with charcoal and suchlike non-conductors of heat; but such are quite distinct from myinvention, which consists, as hercinbefore stated, in forining` theinner casing of sash-work in which sheets of glass are placed, and thenfilling in the sash-work flush, as shown, with plaster or plasticcompound, thereby enabling the casing shown in Fig. 4 to be, after theplaster or plastic compound has set and hardened so that the sash-work,glass, and plaster or plastic compound have become practically one 'andthe same solid piece, put bodily into the outer casing, A, after thesame has been constructed the required size for it. whenever it isdesired to clean out the refrigerator, the inner casing may again betaken out, and restored when the operation of cleaning is finished.Consequently my invention has a clear distinction from the said formerinventions.

Vhat I claim, and wish to secure by Letters Patent, is as follows:

l. As a new article of manufacture, a refrigerator formed of an outercasing and inner lining1 or casing, said inner lining` or casingconsisting of sash-work, glass, and plaster or GEO. R. PROVVSE.
